There is a simple version to my question, and a complex version. First, the simple version: I want to generate label names by combining a constant string with a counter's value, something like what is done here:



But when I use this, I get a bunch of warnings about multiply-defined labels. It appears they are all getting named the same thing, using the highest value of counter foo. I guess this has to do with the order TeX evaluates things, as suggested by the answer in the link above. Can anyone do a better job explaining this than the response there?

Now the more complex problem, and what I'm really trying to solve: I'm using the lineno package, which has a \linelabel command that works much like \label. You can get the label's line number using \ref{labelname}. It's these labels I really want to number with a counter. I tried applying the linked solution to \linelabel, but I couldn't get it to work. Any ideas how I might do this?

Hang on a second. After thinking about this again, if you need to type \ref{bar:7} to get the counter number 7, why do you need the label in the first place? – Will Robertson Dec 2 '10 at 17:12
  1. You need to use \refstepcounter instead of \stepcounter. This must be badly documented somewhere — lots of people make this mistake.

  2. You might need to save the linelabel counter to a counter of your own, decrement it, and then \refstepcounter it again. (Hope this explanation's not too brief; I'm in a hurry.)

your \addnextlabel works fine in standard latex (for me) -- you're presumably using one of the myriad packages that fiddles with the reference mechanism.

i would expect


to do the job for you, if my hypothesis is correct.

The original \addnextlabel doesn't work to refer back to the labels that it's trying to set. – Will Robertson Dec 2 '10 at 17:14
